Definitions

  • the present invention relates generally to antennas, and particularly to a method of production of an antenna pattern.
  • antennas On way of making inexpensive antennas is to electrolytic build up antenna patterns, which however is limited in choice of 3D shape details for the antenna pattern.
  • One way of making advanced 3D shape details of antenna patterns is to use ink jet printers, laser activation devices, or similar devices, which however tends to make the antennas expensive to manufacture.
  • An object of the present invention is to provide a method of production of antenna patterns that makes antennas less expensive to manufacture.
  • An antenna pattern for a portable radio communication device such as a mobile phone, personal digital assistant, portable computer or similar device, is created by a laser activation device and a following metallization process.
  • the antenna pattern is created by an ink jet printer or similar device.
  • the creating device is preferably capable of manufacturing 3D shaped antennas also having via holes.
  • the antenna pattern is in this embodiment exemplified having a predetermined general outline 1, preferably a generally rectangular outline 1 with a preferred L-shaped slot 2. Further, the antenna pattern is preferably provided with one or more feed points 3 and/or one or more ground points 4.
  • the inner part of the predetermined general outline of the antenna pattern is for a plurality of inner portions empty by not being created by the laser activation device, which reduces the cycle time of the laser activation device considerably, at the same time largely maintaining antenna performance.
  • the antenna performance is more affected by empty portions close to the feed point and ground point, whereby the antenna pattern preferably is more densely activate close to the feed point and ground point, respectively. Portions close to sharp corners and the edges are preferably also somewhat more solid than the rest of the antenna pattern (not illustrated) to improve the antenna performance.
  • the plurality of empty inner portions of the antenna pattern not activated by the laser activation device is preferably rectangular-shaped having rounded corners, such as illustrated in Fig. 1b, which is advantageous for manufacturing and for antenna performance.
  • the plurality of empty inner portions are rectangular having sharp corners as illustrated in Fig. la, are circular as illustrated in Fig. 1c or having other shapes such as irregular shapes.
  • the empty spaces of the antenna pattern can be used to position discrete components therein, to save space in a portable radio communication device.
  • the present invention is to its most advantage for antennas having large connected areas, wherein great reduction of cycle time can be achieved by the present invention, also other antennas having small tongues and other complex structures benefit from having empty spaces.
  • a laser activation device modifies an organic-metallic complex such that only the modified portions are metallized during a later metallization process.
  • the return loss and total efficiency was measured for an antenna having a general outline of a rectangle.
  • the measurement was performed for a solid antenna pattern, an antenna pattern having a grid size of 1 mm, a grid size of 2 mm and a grid size of 4 mm, respectively.
  • the bandwidth at -6 dB was largely unaffected of the grid size, even if the centre frequency was somewhat shifted. Such a frequency shift is however easily compensated for by matching of the antenna. Also for the total efficiency of the antenna the bandwidth is largely unaffected.
